PRINT DRIER.

Application filed November 13, 1924. Serial No. 749,729.

-To all whom it may COW/66TH.

Be it known that we, LEWIS NATHANlEL HAixns and Emma Inwrx, citizens ofthe United States, residing at Kla'math Falls, in the county of Klamath,State of Oregon, have invented certain new and useful Ini- .provementsin Print Driers; and we do hereby declare the following to be a full,clear,

and exact description of'the invention, such.

as will enable others skilled inv the art to which it appertains to makeand use the same.

This invention relates tov new and useful improvements in dryingdevices, and particularly devices for drying photographic prints,negatives, or the like. One object of the invention is to provide adevice of this character whereby the prints will be more effectivelyandquickly'dried than with devices of this character heretofore.

Another object is to provide a device of this character by means ofwhichthe' prints will be flat when dried, the ordinary curling thereof,toward the fil1n-face,being obviated' Other objects and advantages willbe apparent from the following description when taken in connection withthe accompanying drawing.

In the drawing; Figure 1 is a front elevation of the device. Figure 2 isa side elevation of the device. Figure 3 is avertical sectional view onthe line 3-3 of Figure 2.

. to the lower side'of the casing, and commit Referring particularly tothe accompanying drawing, there is shown a comparatively shallowcylindrical casing 10, and connected nicating therewith, is arectangular box 11, in which is disposed the heating element 12, whichmay be the electric heating coils shown, or other suitable means- Acover 13 is removably engaged on the open side of the v casing, and hasa depending poition 14 engaging wlth the box 11, said cover havingacentral opening- 15, straddled by the'handle 16. Fixed to the center ofthe outer face of the other wallof the casing is a bearing 17,

' and rotatably supported in this hearing is the shaft-18. On the outerend of the shaft is a belt wheel 19, for receiving power from anysuitable source. On the rear wall of the casing, and secured to sa dbearing, is a depending clamp 20 which is adapted to be secured to theedge of a table, bench, or other suitable support, for holding thecasing in proper upright position." 1 I Secured to the shaft 18, withinthe casing,

and radiating from the shaft, are the curved screen 23, which is of thesame width as that of the blades of the wheel.

In the side of the casing, justabove the upper end of the box 11, is anopening'24,

which is controlled by thehinged door 25.

Carried by the outer face of the door, and extending at right anglestherefrom, is a notched arm 26, on which is slidably ar ranged a weight27. This door is ada ted to be blown open, by the blast of air rom thefan, as said fan rotates, to permit the escape of the excess of air, theweight being adapted to regulate the degree of pressure at which thedoor will open.

The normal tendency of a drying print is to curl toward the film side orface of the paper, thus rendering the handling of the prints difficult.If, when the prints are wet the film sides are placed against the olishesurface of a sheet of glass, enamel'e metal,

' or the like, no our], to any appreciable ex tent, will be present inthe dried print. i In the present devi e r; number of longitudinallycurved plates '28 are arranged to slip between the blades of the fan, insuch manner that one end of each plate is en gaged beneath the strip 22,and the other end engaged within the angle between adja cent blades. Tothe concave face of this plate is applied the film face of the wetprint,and the plate slipped into, its lace between an adjacent pair of blades0 the fan wheel.

The source of heat being in operation, the

fan wheel is rotated, and as the fan blades,

pass across the open top of the box 11, they scoop up a quantity of hotair,-from the box, which air is evenly distributed over the printbetween the blades. The prints having been properly dried, the'plates 28are removed from the fan and the prints stripped from said plates. Theprints will f shaft of the fan.

have no tendency to curl toward the film faces th'ereofi I 'hile wehave, shown the fan wheel driven by a belt, it will beund'erstood that amotor may be connected directly to the In the bottom ofthe box areformed .a plurality of openings 29, and pivoted on said bottom, inposition'to be swung into l0 and out of covering relation to theopenings, are the plates or doors 30,. such can struetion permittingexcess heat being forced, by the fan, out of said openings, therebypreventing too great heat on the prints. m w

\Vhat is claimed is:

1. A print drier including a casing, a. fan in the asing, a heatingmeans mounted in positi\ to discharge into the casing, and wet printholding means removably mounted on the fan. I

2. A print drier including a casing, a rotatable fan in the casinghaving blades mounted in the casing, a receptacle dis-.

posed below and communicating with the casing, a heating means in thereceptacle,

on the blades of the fan.

and wet print holders removablyfmounted 3. A print drier including acasing, a. fan wheel mounted to rotate in the casing and having commonlycurvedblades, a receptacle connected to the lower portion of thecasing'and opening thereinto, a reticulated rim'on'the fan wheel, andcurved plates for holding wet prints detachably engaged with the innerand outer ends of the blades.

4. A print drier including a casin a fan wheel in the casing, said fanwiieel including radial curved blades, ofiset transverse strips securedto the outer' ends ofthe said blades, and wet print holding curvedplates disposed between adjacent pairs of f i blades and each having anend engaged within the inner angle between blades and its outer endengaged beneath a transverse strip.
